so i changed the plugs but.....

it still dosent feel right....the car was hesitating and had low power...its better now with the ngk plugs i put in....changing spark plugs on the 8 is hella harder then changing them on my 7.....anyway....when i took out the plugs my friend took a look at the them and said they were smelling like gas...with i guess is normal...but he said its running to rich...but then again thats normal for a RX...then then after i changed all my plugs...i started to smell gas....coming from the car when i stand outside of it....which didnt happen before....so my question is...since my car is a 2007 model....maybe i should change the coil packs or make sure the ecu is on the most current flash...either way how much would it be for coils or to update the flash? also...everytime i touch the car when i turn it off and get out i get shocked....im thinking this is a lose ground? but this only started happening after i changed the plugs.....maybe a...plug wire is loose....

Miles on the car? Miles on the engine? have you checked the cat, sounds like it might be on its way out if you are smelling gasoline fumes. Coil's could be the cause of issues as well.

I have an 07 and it had strong gas smell for several minutes after starting.

Put on BHR ign upgrade at 22k miles, kept original plugs in to test BHR ign, and the gas smell went away.

I'll change plugs when it seems it needs it or at 30k to 37.5k miles like the book says.

If the coils work on a car, the plugs will work great, and spark will be even better as the plug gap gets larger up to the point of misfire.

I changed the plugs on a Dodge Dakota that was running fine at 65k miles, and the plugs had the right deposit color, but were worn to .060 inch instead of the .040 initial gap.

Like I said the truck was running fine, and gas mileage was good, but I knew the plugs would misfire if they wore much more.

This forum is full of these stories, but the solution starts upstream.

Mazda made a big mistake with the inferior coils they put on 8's.

They mention changing plugs in the book like the wear item they are, but never a mention of coil checking.

In my 07 6spd auto the engine runs at a low 2500 rpm mostly because I drive 400 miles to any track day 4 times a year, and never runs over 7k rpm.

However, I had one severely burned coil when I put my BHR ign on last month at 22k miles.

They should cover coils under warranty, which they might at low miles, but you'll just get another inferior design coil.

These coils are surely penny wise and pound foolish on Mazda's part in that they eventually fail, carbon up the seals, ruin the cats, and generally scare hell outta anyone liking the RX8 design.

Also, let me guess, you have cloth seats in your car. When you get out on a dry colder day, you generate static electricity when you slide in or out of your 8. I've never heard of being shocked by any kind of bad wiring in the car, because the metal car grounds it first one way or another.

Out here in West Texas, I've seen the humidity drop to appox 7%, and you're sparking everywhere you go. Especially in inferior floors in Sam's and Wal-Mart.

Your plugs should not look like that. I would replace your ignition coils if you have 40k+ on them. Those plugs are shot.

As for the gas smell does it go away after teh car is warmed up? If it does then its just simply that your cat is not functioning yet. The convertor only works when its hot, when its cold it does absolutely nothing.

You should get the BHR ones, they are not the cheapest but they will last you a long time. Rather than possibly replacing oem coils multiple more times. They are also much better than oem.

http://blackhaloracing.com/products-...nition-system/

hundreds of people have bought these and as far as I know most if not all of them have had nothing but good things to say. Maybe try PMing someone from BHR(lots on this forum, flashwing, charles r hill, etc) and see if they could give you any type of special deal on them. No clue if they could or not.

is this inside or outside of the car? I see you put outside, but there is the possibility the smell could be inside as well. If its inside of the car then it could be your fuel pump. A lot of people have needed to replace this part. My suspesion is that the ethanol in fuel could be eating through the pastic housing but there could be many many reasons. Also check the fuel line running to the engine. I know that this is usually only a culprit on vehicles that have had an engine replaced and they did not replace the fuel line but still maybe it wasn't set perfect, or you got a faulty line. The only way to really find the culprit if it isn't that the engine is to rich is just trial and error. On that note is there anything aftermarket on your car? Anything at all that would affect the engine, or its components?

As for your suspesion on the plugs and wires. When you get the new coils in I would remove everything completely. Re install and Re torque the plugs. Also I didn't see you type that you changed the wires? Order a set of wires if you didn't already and install new wires with your new plugs.

With the right tools replacing the spark plugs on your 8 is easy. By looking at the picture of your plug 3 things come to mind. You recently flooded the car by shutting it off while cold, your ignition coils are failing, or loose spark plug wire. How many miles do you have on your ignition coils. If this was my car I would buy new ignition coils, spark plugs which you have already and a new set of spark plug wires.

no the car is completely stock and judging from what the plugs looked like when i pulled them out id say the coils that in there now are the original coils....i just took a look at the bhr coils they seem to be really good but $400+ is a bit out my price range.....so i guess ill have keep searching....now spark plug wires i can do..since the standard wires arent that much but i guess standard wont since this car runs so damn rich.....plus yea the reason i kept getting shocked was from static....my friend lol'd at me >.<

OEM Ignition coils $179.80 plus shipping from http://www.finishlineperformance.com...cat=273&page=1

OEM MSD Plug Wires $60.00 from http://blackhaloracing.com/products-...sd-plug-wires/

Where do you live? When the weather gets cold there is more static electricity. I get shocked sometimes when getting out of my car too, and I am not getting bad mpg's. There are other factors of static electricity like the clothing your are wearing the contact between you and your seat.

They forgot to mention the "coil" as part of maintenance. totally Marketing's fault.

This is also why they updated the part twice. B revision handles stress much better than original and A. Sure they don't last as long as everybody wants. Consider FC coils last 4-6 times longer(its different design, but whatever) but for regular street use just change them every 20-30K I don't see anything wrong with it.

nycgps,

You get it, and I like your oil ideas, but really, ignition coils should be life of car stuff.

A Japanese company like Mazda was embarased (sic) to say that their coils were not up to snuff.

It should only be the plugs that get hammered, and need maintenance in most cars.

goto oriellys. They were selling coils for our car with a lifetime warranty no questions asked return policy. The coils in my car are closing in on 70K and they are functioning just fine. I believe they were signifigantly cheaper if you buy from orileys as well.

Really, the life of the car? I'm guessing the battery should last that long too then. Every car will need coils eventually. Yeah the 8 goes through them faster than most, but no coil lasts forever.

I would suggest that you replace your coils too. Hell, they have a lifetime warranty. 70k is either bullshit, you don't know what "functioning just fine" is, or you are one lucky bastard. I'll pull for one lucky bastard to be nice.



OP, order new coils and wires. If you can't afford the BHR system, check with some of the other vendors as well. Mazmart always has good prices on them as well. Your car will thank you. A weak ignition can lead to much bigger problems with the renny.

Could be a clogged cat. That sounds typical for a clogged cat. converter. It should be covered under your emissions system warranty.

You can bring in the car to your dealer and they will diagnose the cat. under warranty at no charge to you. I would generally recommend just replacing the coils as a maintenance item but since cash is a concern for you I recommend you take it to a local dealer recommended by guys in your area and complain about the low power and gas smell. They should check both your cat. and coils and determine which is the problem.

Make sure you tell them you put in new plugs!

If they tell you it's coils and they are going to charge you just say no and swap them yourself.

If it's the cat. best case is you get a new cat free of charge and you would not be charged for a diagnosis.

Search the regional section of this forum where you live and find out which dealers near you are the best to go to and schedule an appointment.
